V-15 Veja x Marni Sneakers VEJA Urca is defined by its innovative design and low-key look. While this white pair’s uppers look like leather, they’re actually wmns from organic cotton covered with resin from corn and castor oil. An eco-conscious icon, the sneaker is accented with a vegan suede ‘V’, then fitted with a bio-sourced, Amazonian rubber sole.
